Paula Abdul has always been tiny, but the new X Factor judge stepped out in Beverly Hills looking noticeably thinner than her usual self.

Has the stress of shooting the premiere season of X Factor possibly gotten to Abdul? We can't even imagine how stressful the shooting schedule can be.

There's also been major drama surrounding the show since it first kicked off production earlier this year. Now that Britain's Sweetheart, Cheryl Cole, has gotten the boot from her hosting gig in favor of Pussycat Doll Nicole Scherzinger, is the network finally happy with the nearly finished product?

Whatever the case for Paula's recent drop in weight, we hope she's staying healthy -- the ex-Idol judge will need all her energy for the busy fall season ahead!
